Figure 2. Differential transcriptional expression of Kir2.1 in rat arteries.
Competitive PCR products were resolved on 2 % ethidium bromide agarose gels. A representative gel of quantitative RT-PCR for Kir2.1 in rat basilar, coronary and mesenteric arteries is shown in A; two-fold serial dilutions of mimic DNA were included in the PCR reactions while the target cDNA (Kir2.1) concentration remained constant. The actual concentrations of target cDNA were calculated and expressed relative to β-actin cDNA concentration (B). Results are expressed as means ±s.e.m.; *significant difference when compared with transcript levels detected in coronary artery.
